15.7.2 Safety Rules to be followed
Note
15-12
•
Position, speed and amplitude of ECG can be altered in the ECG menu under the
ultrasound image.
•
With standard setting of the electrodes (white = right arm, black = left arm, green = right
leg) lead I is displayed. Other electrode arrangements may be necessary (lead II, III), if
amplitude supplied by lead I is too small.
•
The ECG module is an integral part of the ultrasound scanner unit. The system may only
be operated in places that go conform with the rules for medically used locations.
•
The power cable of the ultrasound scanner system must not be connected to a damaged
socket. The socket must be equipped with a grounded conductor. If necessary a
potential equilibrium must be connected.
•
Only the patient cable provided by GE Healthcare may be used. Consequently, only
push-button electrodes may be used.
•
Take care that neither bare parts of one of the electrodes nor the patient can get in
contact with conductive parts (e.g., metal parts of the examination bed, trolley, or
similar).
•
This device must not be used for an intra-operative application on the heart.
•
If the use of a HF surgical unit with simultaneous connected ECG electrodes becomes
necessary, a maximum distance of ECG-electrodes from the surgical field and a correct
position and contact of the neutral electrode of the HF surgical unit must be observed
(avoidance of burning risk).
•
Note that stimulation current devices can influence the ECG signal.
•
If several instruments are simultaneously used on the patient, all these instruments must
be connected to an appropriate potential equilibrium (avoidance of lead currents).
•
If the use of a defibrillator becomes necessary, there must be no ECG adhesive
electrodes and no conductive paste between the contact positions of the defibrillator
plates (avoidance of current bridges; the signal input of the ECG module is defibrillator-
safe).
•
After the defibrillator stimulates the patient, the ECG needs 4 to 5 seconds for recovery.
•
Conductive parts of electrodes and associated connectors for applied parts including the
neutral electrode should not contact other conductive parts and earth.
•
Be aware that the leakage current of the entire system including any / all auxiliary
equipment must not exceed the limit values as per IEC60601-1-1 resp. other valid
national or international standards. All equipment must comply with UL, CSA and IEC
requirements.
Follow the User Manual of the defibrillator. Do not touch the patient during defibrillation.
